Generally, rules at the MTA (exim) level are global.  Rules at the LDA 
(dovecot-sieve) level are user-controlled.  Mail user agents that support 
sieve allow users to set their own personalized filtering and sorting 
rules.  I am not aware of any mail user agents that allow individual 
users to set filter rules at the exim level that would only apply to one 
user.

Perhaps this background reading would be useful in furthering your 
understanding:
